Abstract

Penelitian ini bertujuan untuk mengetahui bagaimana pengaruh struktur aktiva dan operating leverage secara parsial dan simultan terhadap struktur modal, serta variabel mana yang berpengaruh dominan terhadap struktur modal pada perusahaan makanan dan minuman yang terdaftar di Bursa Efek Indonesia. Untuk mencapai tujuan tersebut, maka penelitian ini menggunakan pendekatan ex-post facto, dengan jenis data sekunder serta menggunakan teknik analisis regresi ganda, korelasi, uji t dan uji F yang sebelumnya diuji menggunakan uji ekonometri dan uji asumsi klasik. Populasi dalam penelitian ini adalah seluruh perusahaan makanan dan minuman yang terdaftar di Bursa Efek Indonesia pada tahun 2007-2010, sampel sebanyak 10 perusahaan. Pengumpulan data dengan teknik dokumentasi dan wawancara.Hasil analisis regresi ganda menunjukkan persamaan: Ŷ = 27,574 + 0,661(X1) - 0,271 (X2), yang berarti bahwa nilai konstanta 27,574 adalah besarnya struktur modal tanpa mempertimbangkan tinggi rendahnya struktur aktiva dan operating leverage (DOL). Koefisien regresi struktur aktiva (X1)  sebesar 0,661 artinya bahwa setiap bartambahnya struktur aktiva 1% akan menyebabkan peningkatan struktur modal sebesar 0,661 %. Dalam hal ini faktor lain yang mempengaruhi struktur modal dianggap tetap. Koefisien regresi untuk Operating Leverage (X2) sebesar -0,271 artinya bahwa setiap bertambahnya DOL 1 %, akan menyebabkan penurunan struktur modal sebesar 0,271 %. Dalam hal ini faktor lain yang mempengaruhi struktur modal dianggap tetap. Besarnya nilai korelasi (r) struktur aktiva dan DOL terhadap struktur modal yaitu sebesar 0,201. Nilai tersebut menunjukkan hubungan kedua variabel tergolong rendah. Sedangkan koefisien determinasi (r2) sebesar 0,041, hal ini berarti perubahan yang terjadi pada struktur modal sebesar 4,1% dipengaruhi oleh struktur aktiva dan DOL, sisanya 95,9% dipengaruhi oleh faktor lain. Berdasarkan hasil analisis Uji-t variabel struktur modal menunjukkan bahwa nilai thitung (0,994) < t­tabel (1,703) dengan nilai signifikan 0,353 menunjukkan struktur aktiva tidak berpengaruh terhadap struktur modal, dan variabel DOL menunjukkan thitung (0,527) < ttabel ­(1,703) dengan nilai signifikan 0,602 menunjukkan bahwa DOL tidak berpengaruh terhadap struktur modal. Berdasarkan hasil analisis Uji-F menunjukkan bahwa nilai Fhitung sebesar 0,570 dengan signifikan 0,572 dan Ftabel senilai 3,33. Dari hasil tersebut menunjukkan bahwa Fhitung lebih kecil dari Ftabel (0,570 < 3,33). Sehingga hipotesis yang diajukan bahwa “struktur aktiva dan DOL tidak memiliki pengaruh secara simultan terhadap struktur modal” dinyatakan diterima (Ho diterima).

Abstract

The fertilizer availability as source of N, P, and K nutrient where plant responsif  was difficult found by farmer. Thefore, It was needed information about nutrient availability in soil properties to know nutrient deficiency of its by maize as plant indicator. The  objective of this research was to study the respons of  N, P, and K fertilizers and the best combination of it on the growth and yield of Maize. The research conducted at Udic Pellusterts in North Isimu Tibawa District of Gorontalo Regency. The experi- mental design was following random block design that consist of 5 treatments with 3 replications. The result of this research showing that minus N, P, and K fertilizers have a significantly effect on plant age polination, the percentage of height stem of  an ear of corn to plant height and dry straw weight but did not have significantly effect on plant height and the weigh of one hundred grain of Maize. To improve the growth and yield of Maize using fertilizing without P treatment were 250 kg Urea ha-1 and 75 kg KCl ha-1 or completely dosage were 250 kg Urea ha-1, 100 kg TSP ha-1 and 75 kg KCl ha-1 as the best fertilizers combination.

Abstract

The research aimed to study effect the application of river sand (RS), coconut coir (CC), and banana coir (BC) on growth and yield of rice (Oryza sativa L.) in Ustic Endoaquert. The research was carried out in a green house using 3 × 3 × 3 factorial design. The RS factor consists of three treatment levels which were 0% RS, 25% RS, and 50% RS. Meanwhile, the CC and BC consist of three treatment levels, where each level were 0 Mg ha-1, 10 Mg ha-1 and 20 Mg ha-1. The results showed that RS, CC and BC applications did not have significant effect on plant height. On the other hand, all ameliorant applications had significantly increase leaf length and the highest percentage increasing was in BC (13.49%). The leaf numbers and tiller numbers had relatively similar pattern, except BC that had significantly increased leaf numbers by 77.69% and amount of tiller numbers by 49.45%. Furthermore, for yield components, RS, CC and BC applications had significant increased panicle numbers by 37.76%. It was only RS and BC that increased panicle lenght and the best increasing of 26.82% on RS. Meanwhile, the BC application only increased the rice grain numbers.[How to Cite: Nurdin and F Zakaria. 2013.

Abstract

The research was aimed to study effect application of sea sand (SS), coconut coir (CC) and banana coir (BC) on the growth and yield of rice (Oryza sativa L.) planted at Ustic Endoaquert soil. The pot experiment was carried out using a factorial design with 3 factors. The first factor was SS consisted of three levels i.e.: 0%, 25%, and 50%. The second and third factors were CC and BC, each consisted of three levels i.e.: 0, 10, and 20 Mg ha-1. Application of SS and BC significantly increased leaf length where the highest increasing  percentage  was  16.47%  which  was  achieved  at  25%  SS  application.  Their  effect  on  leaf numbers and tiller numbers were relatively not similar pattern where leaf number only increased about 65.52% by BC application, while tiller numbers only increased about 10.77% by SS application. Furthermore, the application of CC and BC significantly increased panicle numbers to 29.53% and 29.05%, respectively compared to control. All ameliorants significantly increased panicle numbers, but the best was CC with the increasing up to 46.49% at 20 Mg ha-1 CC compared to SS or BC application. However, only coconut coir significantly increased the rice grain numbers.Keywords: Banana coir, coconut coir, rice plant, sea sand, vertisol [How to Cite: Nurdin. 2014.

Abstract

Rainfed paddy soils that are derived from lacustrine and include of E4 agroclimatic zone have many unique properties and potentially for paddy and corn plantations. This sreseach was aimed to: (1) study the soil development of rainfed paddy soils derived from lacustrine and (2) evaluate rainfed paddy soils potency for paddy and corn in Paguyaman. Soil samples were taken from three profiles according to toposequent, and they were analyzed in laboratory. Data were analyzed with descriptive-quantitative analysis. Furthermore, assessment on rainfed paddy soils potency was conducted with land suitability analysis using parametric approach. Results indicate that all pedon had  evolved with B horizons structurization. However, pedon located on the summit slope was more developed and intensely weathered than those of the shoulder and foot slopes.The main pedogenesis in all pedons were through elluviation, illuviation, lessivage, pedoturbation, and gleization processes. The main factors of pedogenesis were climate, age (time) and topography factors. Therefore, P1 pedons are classified as Ustic Endoaquerts, fine, smectitic, isohypertermic; P2 as Vertic Endoaquepts, fine, smectitic, isohypertermic; and P3 as Vertic Epiaquepts, fine, smectitic, isohypertermic. Based on the potentials of the land, the highest of land suitability class (LSC) of land utilization type (LUT) local paddy was highly suitable (S1), while the lowest one was not suitable with nutrient availability as the limiting factor (Nna). The highest LCS of paddy-corn LUT was marginally suitable with water availability as the limiting factor (S3wa), while the lower LSC was not suitable with nutrient availabily as the limiting factor (Nna).
